Occurrence and evaluation of damage caused by the root-knot nematode, Meloidogyne javanica, on Desmodium heterocarpon in the Llanos Orientales of Colombia
A field infestation of Meloidogyne javanica on Desmodium heterocarpon is reported for the first time in the Eastern Plains (Llanos Orientales) of Colombia. An experimental planting of 59 accessions of D. heterocarpon was evaluated for root galls, chlorosis, stunting and dieback caused by M. javanica...

| description | A field infestation of Meloidogyne javanica on Desmodium heterocarpon is reported for the first time in the Eastern Plains (Llanos Orientales) of Colombia. An experimental planting of 59 accessions of D. heterocarpon was evaluated for root galls, chlorosis, stunting and dieback caused by M. javanica. Forty-three accessions were found to possess practical resistance. Above-ground appearance was an unreliable guide to the extent of root galling suggesting that a direct examination of roots is necessary. |
